Energy Use and Emission Reductions in Brussels

TML built a transparent transport simulation
model for the BIM-IBGE

The Brussels Region, like many other metropolitan regions and cities,
faces environmental challenges with respect to energy use and emissions.
To investigate the effects of different policies aimed at reducing
emission and energy use, the environmental administration of the Brussels Region asked
TML and 3E to build a transparent model. TML modelled the transport
sector while 3E, an energy consulting company, modelled the other
sectors.

The transparency of the model was a major issue as
the administration itself will use the model to carry out
simulations.

The transport model takes all major pollutants and
greenhouse gases into account. It also accounts for energy use
and all kinds of costs,
including time costs and taxes. The model is able
to take technological measures as well as various other pricing measures
into account. The model calculates impacts on transport volumes, modal
shares and emissions.

The model can, for example, simulate the effects of the following
policies:

road user charging

improved public transport (travel time or costs)

cheaper public transport

increased renewal of cars

…

The model is inspired by the European environmental
transport model TREMOVE and
can be adapted to other cities.
